The transtelephonic monitor is specifically designed for transmitting ECG tracings over a landline phone connection. This type of monitor allows physicians to receive real-time or recorded ECG data from patients located in remote areas, facilitating continuous monitoring without requiring the patient to be physically present in the hospital or clinic.

This capability is especially valuable in situations where patients may have limited access to healthcare facilities, enabling timely diagnosis and intervention based on the transmitted ECG data. The technology utilizes telephone lines to relay the information, making it reliable and accessible for healthcare providers.

In contrast, telemetry monitors often utilize wireless technology for real-time monitoring but are typically used in settings where the patient is present, such as a hospital. A 12-lead ECG monitor is commonly used in clinical settings to capture a comprehensive view of the heart's electrical activity at a single point in time, rather than for continuous remote monitoring. The Holter monitor, on the other hand, provides extensive monitoring of a patient's heart activity over a period of 24 hours or more but records data for later analysis rather than transmitting it in real time.
